Poisel, Alexander; Meier, Alexander; Bach, Dietmar | The application of the guideline for the geotechnical design of underground structures with TBM excavation in Austria | Geomechanics and Tunnelling | 1/2023 | 38-46 | Topics |
KurzfassungIn 2013, the Austrian Society for Geomechanics published the Guideline for the Geotechnical Design of Underground Structures with TBM Excavation. The Guideline contains general procedures for the geotechnical design and construction. In the design phase, the first steps are evaluating different ground conditions by classifying different ground types, different ground behaviours, their categorization into ground behaviour types, and the determination of construction measures derived from the ground behaviour. On this basis the expected system behaviour in each system sector of the tunnel boring machine (TBM) is predicted and described in detail to enable comparison in the construction phase. In the construction phase, geotechnical relevant ground parameters as well as observations regarding the actual system behaviour are recorded and compared with the assumptions of the design. The geotechnical design is updated continuously based on the encountered ground conditions and geotechnical observations. The improved quality of the geotechnical model allows an optimization of the construction while meeting all safety and environmental requirements. In the first part of the article, the general procedures of the guideline are described and parameters to describe the system behaviour in each system sector adequately are listed. In the second part of the article, the implementation of the guideline during design and construction at the Semmering Basetunnel in Austria is described. x | |||||
Fuchs, S.; Kaitna, R.; Scheidl, C.; Hübl, J. | The Application of the Risk Concept to Debris Flow Hazards | Geomechanik und Tunnelbau | 2/2008 | 120-129 | Fachthemen |
KurzfassungDebris flows present a serious hazard in alpine regions, where natural environment meets the space of human interest such as settlements and infrastructure. In the past various measures have been developed to protect human life and property. However, a complete protection from damage is not possible, also due to limited financial resources of public fund providers. Therefore, the concept of risk management was adopted from technical sciences as an alternative and sustainable protection strategy, and was increasingly implemented in Alpine countries within the last decades. This paper provides an introduction to the state of the art in risk analysis for debris flow hazards, including an overview of different but complementary methods for debris flow risk analysis at different scales. x | |||||

de Bouw, M.; Wouters, I.; Lauriks, L.; Collette, Q.; Younes, A. H. | The Ardant truss: a forgotten rival of the well-known Polonceau truss | Steel Construction | 2/2010 | 83-89 | Articles |
KurzfassungIn 1839 the engineer Camille Polonceau invented the structurally efficient Polonceau truss. However, for a long time architects refused to leave iron structures exposed in public buildings for aesthetical reasons. Despite this, engineers acknowledged the ample structural opportunities of iron roofs, which urged them to experiment with curved trusses in order to avoid the bar roof trusses so reminiscent of industrial buildings. Nevertheless, today everyone knows the Polonceau truss, whereas few are familiar with its aesthetical counterpart: the Ardant truss. x | |||||
Pelke , Eberhard; Kurrer, Karl-Eugen | The art of major bridge-building - Hellmut Homberg and his contribution to multiple cable-stayed spans | Steel Construction | 4/2012 | 251-265 | Reports |
KurzfassungBased on findings from Büchenauer Bridge (1956), the North Elbe Bridge in Hamburg (1963) and the bridge over the Rhine at Leverkusen (1965), Homberg designed and engineered the Friedrich Ebert Bridge across the River Rhine. This was the first bridge in the world with cables that distribute instead of concentrate the load transfer, and thus define the bridge deck as a continuous, elastically supported element and not as a beam on point supports. x | |||||
Jaeger, Falk | The Art of Masonry / Mauerwerkskunst - Kunst des Mauerns | Mauerwerk | 1/2019 | 50-54 | Berichte |
KurzfassungBrick masonry is not only a question of building physics, building construction and durability, i.e. sustainability, but has much to do with aesthetics and making sense, which may have been forgotten in modern architecture with its absolute lack of décor. Masonry as an art form has been scarce since the era of brick expressionism. Recently, there have been some exceptions - and thoroughly welcome. The “Fjordenhus” in Vejle, Denmark, is an astonishing example. x | |||||

Volkmann, Günther M.; Reith, Marco; Berner, Thomas | The AT - Casing System / Das AT - Hüllrohrsystem | Geomechanics and Tunnelling | 1/2012 | 41-48 | Topics |
KurzfassungRecent developments show that special measures like pipe umbrellas are being used more often in continuous tunnelling, and already have to be planned during the design phase. The AT - Casing System, already in successful use for some decades in sequential tunnelling and in geotechnical engineering, has recently seen increasing use in TBM tunnelling. According to the type of pipe used, the system can be used to support the surrounding ground, for grouting measures or for drainage. An example calculation is intended to demonstrate the potential of advance support over a fault zone and point out some possible optimisations of the load-bearing capacity. Finally, the system is presented through the example of the New Kaiser Wilhelm Tunnel in Germany. On this project, the AT - Pipe Umbrella System was combined with the AT - GRP Injection System in order to gain the advantages of both. x | |||||
Raderbauer, B. | The autobahn ring Biel east branch / Autobahnumfahrung Biel Ostast | Geomechanics and Tunnelling | 6/2010 | 699-710 | Topics |
KurzfassungThe Biel autobahn ring closes one of the last gaps in the Swiss autobahn network, and the east branch of this ring requires two twin-bore tunnels in difficult and variable geology. All four tunnel bores are being driven by an earth pressure machine with 12.6 m diameter. Right at the start of the tunnel section, the route passes under a canton road and the main line of the Swiss federal railways SBB. This article describes the contractor's “table bridge” proposal for the section under the canton road and the railway line and the work of the earth pressure machine and the transfer of the TBM between two tunnels is described in more detail. x | |||||
Gschnitzer, Heinz | The Baltic-Adriatic corridor and the measures of the ÖBB to upgrade the Südbahn line / Die baltisch-adriatische Achse und die Maßnahmen der ÖBB im Rahmen der neuen Südbahn | Geomechanics and Tunnelling | 6/2013 | 635-640 | Topics |
KurzfassungThe Baltic-Adriatic Corridor, one of the most important north-south routes in Europe and the easternmost crossing of the Alps, connects the Baltic with the Adriatic. 455 km of the Baltic-Adriatic Corridor runs through Austria. Currently it only meets the requirements of an efficient international long distance transport connection in a few stretches. This is due above all to topography: in Austria, the corridor crosses the Alps. In addition, large sections of the line date from the era of the Austro-Hungarian Empire and only a few sections have been updated since then. Three bottlenecks on Austrian territory in particular massively limit the efficiency of the corridor: the Vienna hub, the crossing of the Semmering and the Neumarkter Sattel, a mountain pass where the railway line bypasses the Graz region in a big loop. To eliminate these bottlenecks in the corridor, Austria is currently pushing ahead with three key projects as well as a number of other construction plans: the Vienna Central Railway Station as a through station, the Semmering Base Tunnel and the Koralmbahn line. But further projects on the Baltic-Adriatic Corridor are also of great importance for Austria: the Terminal Inzersdorf, the upgrading of the Pottendorfer line, the repair of the line from Mürzzuschlag to Bruck/Mur and the improvement from Bruck/Mur to Graz. x | |||||
Obernhuber, Pius | The base area of Zillergründl Dam / Der Aufstandsbereich der Sperre Zillergründl | Geomechanics and Tunnelling | 5/2012 | 464-472 | Topics |
KurzfassungIn high arch dams situated in wide valleys, the water load has the effect that the vertical forces from the self-weight are redistributed from the centre of the dam toward its flanks. As a consequence, the normal force in the foundation area of the central dam blocks is reduced and a gap may open in the base joint, which widens even further due to uplift pressure. x | |||||

KurzfassungThis paper describes the Hradecky Bridge across the River Ljubljanica and the hinges used in its three-hinged arch. The bridge was constructed at its original location in 1867, but due to its prefabricated structure and particular type of hinges it was possible to take the bridge completely apart and to reconstruct it at two other locations in 1932 and 2011. x | |||||
Richter, Sascha; Cudmani, Roberto O.; Slominski, Cezary | The behavior of a spread footing over reinforced ground with gravel interface during a strong earthquake | geotechnik | 3/2011 | 193-204 | Fachthemen |
KurzfassungFor the design of the Golden Ears approach bridge in Vancouver (Canada), a spread footing over a pile-reinforced ground with gravel interface was considered as an alternative to a conventional pile foundation. The mechanisms governing the behavior of the spread footing during strong earthquake events have been investigated in a numerical Finite-Element (FE) analysis using a (visco-) hypoplastic constitutive relationship. The FE model includes the soil, the piles, the footing and the gravel layer. The superstructure and the pier are represented by a point mass attached to the end of a vertical beam. Material parameters for the soil models were derived from available field and laboratory tests. The numerical model was validated using results from a large-scale in-situ test with a footing above a single pile. The goal of the numerical study was the investigation of the influence of pile spacing and gravel layer thickness on the dynamic response of the footing, the superstructure and internal pile forces during a strong earthquake. A significant kinematic decoupling between footing and improved soft soil through the gravel layer did not occur in the simulations. Analysis results show that the internal forces in the reinforcement piles are considerably smaller compared with those in a conventional pile foundation, particularly in the upper part of the pile. The pile spacing was found to have a minor influence on the internal pile forces. In the range investigated, a dependence between the bending moments and shear forces in the piles and the thickness of the gravel layer was not observed. x | |||||
Schmidt, Ulf; Bakeer, Tammam; Jäger, Wolfram; Brameshuber, Wolfgang | The bending strength of masonry / Biegezugfestigkeit von Mauerwerk | Mauerwerk | 1/2015 | 27-39 | Fachthemen |
KurzfassungBending strength of masonry becomes an important design aspect especially when the walls subjected to lateral loads like, cellar walls which are subject to earth pressure, and façades/ infill walls which are exposed to the wind actions. Bending strength is required wherever the applied load is perpendicular to the wall. It is also required in non-load-bearing partition walls, where the load applied in both the normal and perpendicular directions. Besides, the tensile properties of the brick/block and lengthwise parameters related to geometry and materials technology also influence the bending strength of masonry. These include the thickness of the wall, the extent of overlap, and both the shear and the tensile strength of the bond. Consideration must also be given to the possible presence of mortar in the head joints, which can significantly increase bending strength, especially where joints fail. In addition to these materials technology factors, it is very important to observe the realistic influence of the boundary conditions. The degree of fixity is among the factors to be considered in calculation models. In this contribution, two aspects are going to be observed and analysed, namely: the principles of bearing capacity under lateral loading alongside the models derived from these for cellar walls and areas of infill; and the influence of materials technology/geometric parameters on the bending strength of masonry. x | |||||
Kohlböck, Bernhard; Griesser, Ewald; Hillisch, Stefan; Birgmann, Harald; Fasching, Alfred | The BIM pilot project Köstendorf - Salzburg / Das BIM-Pilotprojekt Köstendorf - Salzburg | Geomechanics and Tunnelling | 4/2018 | 325-334 | Topics |
KurzfassungThe new approx. 21 km long section between Köstendorf and Salzburg is one of the last major milestones in the upgrading of the Salzburg-Vienna rail corridor to four tracks. The section comprises a multitude of different civil engineering structures, posing high demands on the interdisciplinary design team. The open sections of the alignment require many over- and underpasses and road diversions. In addition, the majority of the section runs underground through the Flachgau Tunnel, which has the particular feature of a tunnel bridge. The aim of the BIM project is to provide a software-independent, integrated model of the whole project. All parties involved in the project collaborate to define the LOD for the terrain, existing building, land use and geological models, as well as the models for the proposed new infrastructure for the open section, tunnels, ventilation control building, bridges, civil structures and drainage. The LoD are defined in parallel with the AIA according to the KISTE infrastructure identification system used by ÖBB (Austrian Federal Railways). At the same time, the BIM execution plans are generated by the team and adapted to the new BIM processes. The opportunities provided by the element-based display and evaluation are anticipated to lead to considerable improvements in the field of interdisciplinary design and visualisation studies. The present article describes the current state of work and provides a preview of future developments. x | |||||

Bergmeister, Konrad | The Brenner Base Tunnel - geological, construction and logistical challenges and innovations at half time / Der Brenner Basistunnel - geologische, bautechnische, logistische Herausforderungen und Innovationen zur Halbzeit | Geomechanics and Tunnelling | 5/2019 | 555-563 | Topics |
KurzfassungThe Brenner Base Tunnel with a total of 230 km of tunnels is a geological, structural and logistical challenge. The transnational project is an additional challenge, considering different planning, approval and construction rules and cultures. From the start of construction in 2007 to the present, today halftime is reached with 100 excavated tunnel kilometers. An overview of selected topics is given in this contribution, such as project optimizations of the emergency areas, geological/geotechnical knowledge transfer from the already driven exploratory tunnel to the following construction lots of the parallel main tunnels, reprocessing and use of Schists as aggregates for the inner lining and shotcrete production, logistics experience with wheel-bound transport vehicles, measurements during construction with laser tunnel scanners and the service life of the tunnel of 200 years with an increased safety concept defined in the guide conceptual design. Preparations and planning are already at an advanced state for the second half of the project, concerning the next excavation lots, secondary linings as well as interior work with the installation of the technical equipment. The construction work is expected to be completed in 2025 and the end of construction is expected at the end of 2028 (2030 in case of risk occurrence). x | |||||
Cremer, Jean-Marie; Del Forno, Jean-Yves; Klein, Jean-François. | The bridge over the "La Fontaine" ravine, Réunion Island | Steel Construction | 1/2011 | 1-6 | Articles |
KurzfassungThis article deals with the design and construction of a bridge on Réunion Island. Its design results from a close cooperation between architect, landscape designer and engineers. It concerns a steel arch bridge with an unusual slenderness ratio of 1:7.5 guided by geotechnics, accessibility to the excavations and environmental and aesthetic considerations. Detailed studies of the wind (numerical calculation of the wind, wind tunnel studies, calculations with turbulent wind) allowed cyclone conditions to be taken into account in the design for top speeds, which can reach nearly 300 km/h. The structure was built using the cantilever method thanks to the addition of diagonals and temporary anchoring tie beams allowing a transitory lattice-type operation. x | |||||
Froli, M.; Ulivieri, E. | The Calculation of Thermal Movements and Eigenstresses in the Leaning Tower of Pisa | Bautechnik | 1/2006 | 23-34 | Fachthemen |
KurzfassungStarting from predicted yearly and daily distributions of the temperature fields induced by climatic actions over the cross-sections of the Leaning Tower of Pisa, the correlated time histories of thermal movements and eigenstresses have been calculated by simply assimilating the monument to a prismatic, inhomogeneous elastic body. Comparisons performed between calculated and measured daily and seasonal thermal displacements evidenced a good prediction capability of the model and its attitude to be used as an interpretation tool to understand also thermal periodical movements in other tower-shaped buildings. x | |||||
